del sry

Just a quick follow up - the main problem was my post processor. Then I switched to swiftsoup and everything is much better now

Ok, the issue is also that I have a complex attributed textview that does a lot of processing to render a comment(replacing various tags, setting font, posts referencing etc) Should have mentioned that I added view.updateIfNeeded and moved replies out as suggested by @StevenPeterson. Feels better now +some animations on scroll Previously instruments showed a few micro hangs. Couldn't see any issues. Will try to dedicate more time to get familiar with it. func scrollToBottom() { guard !viewModel.processedPosts.isEmpty else { return } let last = viewModel.processedPosts.last!.post.num scrollProxy?.scrollTo(last, anchor: .bottom) DispatchQueue.main.asyncAfter(deadline: .now() + 0.08) { withAnimation(.easeOut(duration: 0.2)) { scrollProxy?.scrollTo(last, anchor: .bottom) } } }

Had to add needsDisplay = true del please
